  • Patent number: 6657637
    Abstract: A coordinate light source calculating unit 103 calculates 3D coordinates for points forming one or more objects and performs clipping. A rendering unit 104 performs rendering and outputs the formed CG image to a frame buffer 108. The coordinate light source calculating unit 103 calculates 3D coordinates forming a video display surface. A perspective projection unit 105 calculates 2D coordinates for each point forming the video display surface. An image decoder 106 decodes a video frame, and an image transform unit 107 transforms this image and outputs it to the frame buffer 108, enabling the video frame to be pasted onto the CG image.

  • Patent number: 6577330
    Abstract: A storage unit 5102 stores image data for a window, and a three-dimensional position calculating unit 5104 calculates a position for the window in a virtual three-dimensional space so that it appears to be at a position inclined in the depth direction. A perspective projection unit 5106 transforms image data so that a window positioned at the calculated coordinates is projected onto a screen in perspective, taking a point in front of the screen as a viewpoint. A frame memory unit 5107 holds image data for the window on which perspective projection has been performed, and a display unit 5108 displays the window on the screen.

  • Patent number: 6331851
    Abstract: It is an object of this invention to provide a graphic display apparatus that reduces the amount of CG data transferred from a server through a network and that allows three-dimensional characters displayed at a terminal to move smoothly. It is another object of this invention to provide an AV synchronous reproduction apparatus that can synchronize an image with a score the tempo of which is changed during reproduction. According to this invention, when a server instructs a terminal to graphically display three-dimensional characters, the terminal provides a plurality of motion patterns. The server then transmits scenario data to the terminal, and the terminal operates based on the scenario data to switch scenes for graphical displays. The terminal switches the scenes for graphical displays with a timing for a home position which is common or substantially common to a motion pattern being executed and a motion pattern to be executed next.
